The following documentation comment has been logged on the website:

Description:
Hello!
It would be good to point out on the pg_basebackup documentation that it
behaves differently from
SELECT * FROM pg_start_backup('label', true, false);
cp -a xxx yyy
SELECT * FROM pg_stop_backup(false, true);
method. One thing discovered was that the latter retains replication slot
information on the clone while pg_basebackup discards all replication slot
information. Not sure if it is a feature or a bug (replication slots
retention is a good thing).
And perhaps there are more such subtle differences?
With best regards,
Kristjan Mustkivi
